Aureolin (Cobalt Yellow) PY40 Ayréoline (Jaune de Cobalt)

This cool yellow's transparent, non-staining properties can effectively warm darker hues without affecting their transparency. Landscape artists rely on Aureolin to successfully glaze their watercolours. Its pigment quality and ability to lift and create soft edges make Aureolin especially useful for portrait and floral painters.

DANIEL SMITH is truly the worldwide leader in watercolours for artists, offering beautiful colours in watercolours—the most from any manufacturer. Many traditional colours are relied upon by all artists, and many "truly unique" colours, created only by Daniel Smith, have become essential to watercolour artists.

PrimaTek Watercolours are made from minerals, often semi-precious minerals, which have been ground into pigments, mixed with gum arabic (the binder), and milled into PrimaTek Watercolours. The first was Lapis Lazuli Genuine in 1998. Since then, many more have been added, including colours such as Amethyst Genuine, Piemontite Genuine, and Serpentine Genuine. Most of these colours have excellent granulating effects that some artists have called "magical."

Luminescent Watercolours have special optical effects that are perfect for subjects possessing a sparkle, sheen, or reflective glow, such as the iridescence of hummingbird feathers or the brilliance of metals.

Cadmium Hues, DANIEL SMITH has developed safe and vibrant Cadmium Hues with the density and richness of cadmium colours without the cadmium pigment. Virtually identical in colour to their namesakes, they are cleaner in mixtures and much more robust in tints. The functional properties—staining power, semi-transparency, and excellent lightfastness—are nearly identical to those of the low-soluble cadmium colours that DANIEL SMITH previously manufactured.

Other Unique Watercolours are created using pigments that DANIEL SMITH has sourced, often from specific locations. These include Burgundy Yellow Ochre, Monte Amiata Natural Sienna, and Roasted French Ochre. Some are created exclusively by DANIEL SMITH, such as Cascade Green, Deep Sap Green, and Green Gold. DANIEL SMITH also finds unusual pigments to create colours like Anthraquinoid Scarlet, Lunar Blue, and Enviro-Friendly Red Iron Oxide, providing more options for artists.
